Answer 1

✅ Para resolver esta questão podemos utilizar a seguinte estratégia de modo a vim montar duas frações equivalentes:

• A)    5, 5

          $\Large\displaystyle\begin{gathered} \frac{2\cdot 5,5}{2} = \frac{11}{2}\Longrightarrow \frac{11}{2}\end{gathered}$

         $\Large\displaystyle\begin{gathered} \frac{4\cdot 5,5}{4} = \frac{22}{4}\Longrightarrow \frac{22}{4}\end{gathered}$    

• B)

             $\Large\displaystyle\begin{gathered} \frac{100\cdot(-0,36)}{100} = \frac{36}{100}\Longrightarrow \frac{36}{100}\end{gathered}$

           $\Large\displaystyle\begin{gathered} \frac{1000\cdot(-0,36)}{1000} = \frac{360}{1000}\Longrightarrow \frac{360}{1000}\end{gathered}$

           

• C)

            $\Large\displaystyle\begin{gathered} \frac{2\cdot 15}{2} = \frac{30}{2}\Longrightarrow \frac{30}{2}\end{gathered}$

            $\Large\displaystyle\begin{gathered} \frac{6\cdot 15}{6} = \frac{90}{6} \Longrightarrow \frac{90}{6}\end{gathered}$

• D)

            $\Large\displaystyle\begin{gathered} \frac{5\cdot 2,2}{5} = \frac{11}{5}\Longrightarrow \frac{11}{5}\end{gathered}$

            $\Large\displaystyle\begin{gathered} \frac{10\cdot2,2}{10} = \frac{22}{10}\Longrightarrow \frac{22}{10}\end{gathered}$

$\LARGE\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{\:\:\:Bons \:estudos!!\:\:\:Boa\: sorte!!\:\:\:}}}\end{gathered} }$

Answer 2

Explicação passo-a-passo:

$a)5.5 = \frac{55}{10} \: \: e \: \: 11/2</p><p>[tex]b ) - 0.36 = \frac{ - 36}{100} \: \: e \: \: \frac{ - 9}{25}$

$c)15 = \frac{30}{2} \: \: e \: \: \frac{45}{3}$

$d)2.2 = \frac{22}{10} \: \: e \: \: \frac{11}{5}$
